Product Description:

The MDD025B-N-100-N2G-040PF0 is a compact AC synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for use with digital drive controllers, it converts electrical power into controlled rotary motion for automated pick-and-place units, small assembly stations, and indexing tables. The motor’s electrical interface and mechanical envelope are arranged for quick installation so motion axes can achieve repeatable positioning under closed-loop control. Its compact format also suits machine sections where available space is limited and short, responsive moves are required during repetitive production cycles.

At standstill, the rotor can supply a continuous torque of 0.60 Nm, allowing the drive to hold loads without thermal overload. Under rated excitation, the shaft reaches 10,000 rpm, supporting rapid cycle times for light tooling. A centering pilot of 40 mm lets the frame seat concentrically against gearheads, and service cables exit on the right side, which can simplify cable routing in tight machine layouts. Position data is produced by resolver feedback, which yields an analog sine-cosine signal that remains stable in electrically noisy environments. With frame size 025 and length code B, the motor occupies little space, and its standard balancing helps reduce added vibration during high-speed operation.

The unit is delivered without a blocking brake, so gravity-loaded axes must rely on external locking devices. A standard housing surrounds the stator and supports a shaft seal that helps prevent grease escape and particulate ingress at the output interface. The single output uses a keyway profile and comes without a side-B shaft extension, which shortens the overall length while retaining positive torque transmission. Power and feedback conductors are routed through a connecting cable with a coupling unit that matches the motor’s coding. This arrangement keeps the electrical connection compact and supports orderly routing around small axes and closely spaced machine components.
